(f) Acute Lymphoblastic Lymphoma in 2nd or greater complete remission. Complete remission includes confirmed complete response (CR) defined as the disappearance of all evidence of disease from all sites for at least 4 weeks. Bone marrow and CSF must be normal and any macroscopic nodules in any organs detectable on imaging techniques should no longer be present. Imaging should include PET scanning. CR will also include unconfirmed complete responses defined as a residual lymph node mass > 1.5 cm in greatest transverse diameter that has regressed by > 75% in sum of the products of the greatest perpendicular diameters (SPD), or any residual lesions in organs that have decreased by > 75%, with a negative PET scan, negative bone marrow and CSF.
